6.1.3 PS/2 Mouse Data Transmission
eKM6211 generates the clocking signal when sending data to and receiving data from
the system.
The system requests eKM6211 receive system data output by forcing the DATA line to
an inactive level and allowing CLK line to go to an active level.
Data transmission frame:
Bit Function
1 Start bit ( always 0 )
2-9 Data bits ( D0 - D7 )
10 Parity bit ( odd parity )
11 Stop bit ( always 1 )
Data Output (data from eKM6211 to system):
If CLK is low (inhibit status), data is no transmission. If CLK is high and DATA is low
(request-to-send), data is updated. Data is received from the system and no
transmission are started by eKM6211 until CLK and DATA both high. If CLK and DATA
both are high, the transmission is ready. DATA is valid prior to the falling edge of CLK
and beyond the rising edge of CLK. During transmission, eKM6211 check for line
contention by checking for an inactive level on CLK at intervals not to exceed 100u sec.
